Design Guide – ProJet 3500

The ProJet has 16 and 32 micron printing capabilities. Yet there are still limits to the printer’s performance for various parts. The purpose of this design guide is to show the results in various simple cases so the users are aware of the expected results.

Features

A supported wall is one that is connected to a supporting surface on at least two sides. The minimum recommended wall thickness for the ProJet is .4 mm. Supported walls smaller than this may warp or otherwise not print to specification.

We have not included the results for these tests because the ProJet does not have errors like the Cube printers in these areas. Overhangs and horizontal spans of any length can generally be expected to be printed as designed.

Of you want to print a part with moving components, it is important to leave a certain amount of clearance between the parts that are intended to move. ‘Horizontal’ refers to the idea that, in an axle/housing pair, the assembly is printed parallel to the build plate.

In our tests, the ProJet required 0.3mm of clearance in order for a horizontally-printed axle to be able to rotate inside its housing.

Of you want to print a part with moving components, it is important to leave a certain amount of clearance between the parts that are intended to move. ‘Vertical’ refers to the idea that, in an axle/housing pair, the assembly is printed perpendicular to the build plate.

In our tests, the ProJet required 0.4mm of clearance in order for a vertically printed axle to be able to rotate inside its housing. It should be noted that part strength is uniform in parts made with the ProJet.
